Originated from the shire of Shrop by a skinny badman.
Pimp 1: "aww man, I just landed on mayfair"
Pimp 2: "don't forget to pay me pimp tax too"
A while later:
Faggot 1: "ahh shit, I'm broke"
Pimps : "ahahahaha, should of paid Pimp Tax Noob!"
2. (This happens most often with women) A person who "taxes" their friend(s)/stalker(s)/lover(s) for hanging out with them/being seen with them. This usually happens when one person likes the other but the feelings aren't mutual. Thus, the person who is being pursued uses the other person to his/her advantage; most likely collecting money or gifts from them.
(A true pimp never files his/her own pimp taxes.)
